Our kid is just three and there's an issue with screens. Even a half hour a day of Khan Academy (currently set to 1st Grade) creates lots of whining at other times in the day for more. A preoccupation with Cars movie characters is OK with toy cars (I guess) but not when there's early morning pleading to watch it again.

But otherwise we're on the same route as you. ATM the kid is heavily into doing jigsaw puzzles on his own (60 pc is about his limit for DIY), and he likes to read to himself now and then.
